NEW YORK (TheStreet) -- Here's what Jim Cramer had to say on CNBC's "Squawk On The Street" Friday:

Cramer said Chart Industries (GTLS) remains one of the best ways to play America's oil and gas boom. He was also bullish on Gap Stores (GPS) , which told a great story when it last reported earnings. GTLS shares ended the week up 6.9% while GPS rose 2.9%.

In the negative camp, Cramer was bearish on Wendy's (WEN) , which is fending off threats from a stronger McDonald's (MCD) . He also took viewers to watch out for FDA investigations into Intuitive Surgical's (ISRG) surgical robots. WEN fell Friday by 3.3% but ISRG was up 8.5%.
